    Abstract: An illumination accessory assembly for vacuum cleaner includes a transparent extension having a first end capable of releasable connection to a vacuum cleaner hose and having a distal vacuum cavity intake end. A LED is positioned so the LED illumination transverses the transparent extension medium and exits the distal end and walls of the transparent extension. The invention provides the operator an illuminated clear line of sight around and through the transparent extension of the area to be cleaned and illuminates the contents in the initial vacuum cavity of the transparent extension for improved operator cleaning efficiency.
